Bond is being caustic so people will pay attention to him. It's his schtick. He reviews Ender's Game and calls it 'pornography'.

His claim is backwards. People instinctively share their favorite stories for signaling reasons. Read Comeuppance if you don't believe me. The urge is probably strong enough that they'll drive across several states to get to a convention to find a receptive group of people with whom they can signal their approval. Indiana Jones fans don't have conventions because they aren't atypical -- most people like Indiana Jones movies.

He is sort of right, though. Anything that's good enough to attract a rabid fan base but still alienate the general public in spite of its virtues is pretty obviously going to have some even bigger faults.

Proust's following is small, rabid, and (being composed mostly of literary critics) is very far out of touch with reality. Why don't we call them a fandom?
